For level bias <= 2047, level _factor = 255*level_bias/2047-255
For level bias >= 2048, level factor = 255*(level_bias-2047)/2048

3.3.10 AGC Gain Limit Set – 0xD1
Description
: The AGC Gain Limit and the AGC Gain Limit Noise Reduction Mode are
two independent blocks which control the AGC gain limit
The AGC Gain Limit Set command allows the user to configure the minimum allowable
difference between the white limit and black limit for AGC histogram processing. A
smaller value allows the maximum gain to be higher (e.g., allows a smaller difference
between the black limit and the white limit). In low-contrast scenes, this smaller value will
